As depicted in
The transferring layer F22 is a layer configured to be transferred to the toner image, and contains foil. The foil means a thinly formed metal such as gold, silver, copper, aluminum, etc. The transferring layer F22 includes a coloring material such as gold, silver, red, etc., and a thermoplastic resin. The transferring layer F22 is disposed between the peeling layer F21 and the adhering layer F23.
The adhering layer F23 is a layer configured to facilitate adhering of the transferring layer F22 to the toner image. The adhering layer F23 contains a material that easily adheres to the toner image heated by the transferring part 50 to be described later, such as, for example, vinyl chloride resin or acrylic resin.
The film unit FU mainly includes a supplying reel 31, a supplying case 32, a winding reel 35, and a memory 100. The holder 90 includes a shaft 43.
The supplying reel 31 is made of resin etc., and includes a supplying shaft part 31A around which the foil film F is wound or to be wound. One end of the foil film F is fixed to the supplying shaft part 31A.
The supplying case 32 is a hollow case configured to house the supplying reel 31. The supplying case 32 is made of resin etc.
The winding reel 35 is made of resin etc., and has a winding shaft part 35A for winding the foil film F. The other end of the foil film F is fixed to the winding shaft part 35A. The winding shaft part 35A is driven and rotated by the main motor M.
The memory 100 is a medium configured to store information and is, for example, an IC chip. The memory 100 has an electric contact surface 120. The memory 100 is disposed in the supplying case 32.
The memory 100 stores specification information and usage history information on the foil film F. The specification information on the foil film F includes information indicating a type of the foil film F, information indicating a width and a position of the foil film F (that is, information indicating the width of the foil film F and information indicating the position of the foil film F), information indicating a length of a new foil film F, and the like. The memory 100 stores information indicating a color of the foil and manufacturer information indicating a manufacturer of the foil film F as the information indicating the type of the foil film F. The usage history information on the foil film F includes information indicating a length of the foil film F having been used, information indicating a remaining amount of the foil film F (i.e., a length of unused foil film F), information indicating a time period elapsed from a time point when the film cartridge FC was used for the first time, and the like. Note that, the length of the used foil film F may be calculated from a rotation amount of the supplying reel 31 or the winding reel 35. The memory 100 can be initialized by, for example, a personal computer owned by a maintenance supplier or the like.
The foil transferring apparatus 1 further includes a reader 150 configured to contact the memory 100 so as to read information from the memory 100.
The reader 150 is disposed in the housing body 21. The reader 150 is disposed at a position where the reader 150 faces the memory 100 in a case where the film cartridge FC is attached to the housing body 21. The reader 150 has an electric contact 151 configured to contact the electric contact surface 120 in a case where the film cartridge FC is positioned at an attachment position (i.e., a position at which the film cartridge FC is attached to the housing body 21). The electric contact 151 is disposed in the housing body 21. The reader 150 is connected to the controller 160.
The first guiding shaft 41 is a shaft configured to guide the foil film F. Specifically, the first guiding shaft 41 contacts the foil film F drawn out from the supplying reel 31 to change a travelling direction of the foil film F. The first guiding shaft 41 is made of SUS (stainless steel), for example.
The second guiding shaft 42 is a shaft configured to guide the foil film F. Specifically, the second guiding shaft 42 contacts the foil film F guided by the first guiding shaft 41 to change the travelling direction of the foil film F. The second guiding shaft 42 is made of SUS, for example.
The shaft 43 is a shaft for adjusting an angle of the foil film F when the foil film F (specifically, the supporting layer F1) is peeled from the sheet S. The shaft 43 is made of SUS etc. The shaft 43 contacts the foil film F guided by the second guiding shaft 42 to change the travelling direction of the foil film F.
The first guiding shaft 41 guides the foil film F drawn out from the supplying reel 31 so that the foil film F is overlapped with the sheet S which is being conveyed in a state that a surface on which the toner image is formed faces downward, from a position below the sheet S. The first guiding shaft 41 changes the conveying direction of the foil film F drawn out from the supplying reel 31 and guides the foil film F so that the foil film travels substantially in parallel with the conveying direction of the sheet S.
The second guiding shaft 42 is a peeling roller that contacts the foil film F travelled through the transferring part 50, and guides the foil film F in a direction separating from the sheet S by changing the conveying direction of the foil film F travelled through the transferring part 50 to a direction different from the conveying direction of the sheet S. The foil film F conveyed through the transferring part 50 in a state that the foil film F is overlapped with the sheet S is guided in a direction different from the travelling direction of the sheet S when the foil film F travels through the second guide shaft 42, and is peeled from the sheet S.
The transferring part 50 is a part for transferring the transferring layer F22 to the toner image formed on the sheet S by heating and pressurizing the sheet S and the foil film Fin a state that the sheet S and the foil film Fare overlapped with each other. The transferring part 50 includes a pressure roller 51, a heating roller 61, a first heater 62, and a second heater 63. The transferring part 50 overlaps the sheet S and the foil film F with each other and heats and pressurizes the sheet S and the foil film F in a state that the sheet S and the foil film Fare overlapped with each other, at the nip part between the pressure roller 51 and the heating roller 61.
The pressure roller 51 is a roller including a cylindrical core bar and a rubber layer, made of a silicone rubber, covering the cylindrical core bar. The pressure roller 51 is disposed above the foil film F and can contact a back surface of the sheet S (that is, a surface opposite to a surface on which the toner image is formed).
The pressure roller 51 is rotatably supported by the cover 22. The pressure roller 51 nips the sheet S and the foil film F with the heating roller 61 at a position between the pressure roller 51 and the heating roller 61. In a case where the pressure roller 51 is driven and rotated by the main motor M, the heating roller 61 is rotated following to the rotation of the pressure roller 51. In such a manner, the sheet S and the foil film Fare conveyed by the pressure roller 51 and heating roller 61 rotating in a state that the sheet S and the foil film F are nipped by the pressure roller 51 and the heating roller 61.
The heating roller 61 is formed to have a cylindrical shape. The first heater 62 and the second heaters 63 are disposed inside the heating roller 61 and heat the heating roller 61. The heating roller 61 is disposed below the foil film F and is in contact with the foil film F. The heating roller 61 can be pressed against or separated from the pressure roller 51 by a pressure-contact and detachment mechanism (not depicted).
The controller 160 includes a CPU, a ROM, a RAM, a nonvolatile memory, and the like, and is configured to perform various controls based on programs prepared in advance. The controller 160 has a function of pressing the heating roller 61 against the pressure roller 51 during a period in which the sheet S travels through the nip part of the transferring part 50, and of separating the heating roller 61 from the pressure roller 51 during a period in which the sheet S is not travelling through the nip part of the transferring part 50.
In the foil transferring apparatus 1 configured as above, the sheets S placed on a sheet tray (not depicted) is conveyed one by one toward the transferring part 50 by the sheet supplying mechanism 11. The sheet S is overlapped with the foil film F supplied from the supplying reel 31 at a position upstream in the sheet conveying direction of the transferring part 50, and is conveyed to the transferring part 50 in a state that the toner image on the sheet S and the foil film F are in contact with each other.
In the transferring part 50, when the sheet S and the foil film F travel through the nip part between the pressure roller 51 and the heating roller 61, the sheet S and the foil film F are heated and pressurized by the heating roller 61 and the pressure roller 51, and the transferring layer F22 is transferred onto the toner image. Note that, in the following description, the transferring of the transferring layer F22 onto the toner image is also referred to simply as “foil transfer”.
After the foil transfer is performed, the sheet S and the foil film F are conveyed to the second guiding shaft 42 in a state that the sheet S and the foil film F are tightly in contact with each other. When the sheet S and the foil film F travel through the second guiding shaft 42, the conveying direction of the foil film F (specifically, the supporting layer F1) changes to a direction different from the conveying direction of the sheet S, and thus the foil film F is peeled from the sheet S.
The foil film F peeled from the sheet S will be wound onto the winding reel 35. Meanwhile, the sheet S from which the foil film F has been peeled will be discharged to the outside of the housing 2 by the sheet discharging mechanism 12.
The film cartridge FC selectively has a first film unit FU1 depicted in
As depicted in
As depicted in
As depicted in
In the memory 100 of the first film unit FU1, “end position” information indicating that the position of the foil film F is a position deviated to one side in the width direction is stored as information indicating the position of the foil film F, and “half width” information indicating that the width of the foil film F is half the size of the third width H3 is stored as information indicating the width of the foil film F. In the memory 100 of the second film unit FU2, “central position” information indicating that the position of the foil film F is the center in the width direction is stored as the information indicating the position of the foil film F, and the “half width” information same as that in the first film unit FU1 is stored as the information indicating the width of the foil film F. In the memory 100 of the third film unit FU3, the “central position” information same as that in the second film unit FU2 is stored as the information indicating the position of the foil film F, and “full width” information indicating that the width of the foil film F is the third width H3 is stored as the information indicating the width of the foil film F.
In the following, the film cartridge FC to which the first film unit FU1 has been attached is also referred to as the first film cartridge FC1. The film cartridge FC to which the second film unit FU2 has been attached is also referred to as the second film cartridge FC2, and the film cartridge FC to which the third film unit FU3 has been attached is also referred to as the third film cartridge FC3.
As depicted in
Regarding the first heater 62, output in a central part 62A in the width direction is greater than output in both end parts 62B in the width direction. Therefore, the first heater 62 is configured to heat the central region 61A of the heating roller 61 more strongly than the end regions 61B.
Regarding the second heater 63, output in both end parts 63B in the width direction is greater than output in a central part 63A in the width direction. Therefore, the second heater 63 is configured to heat the end regions 61B of the heating roller 61 more strongly than the central region 61A.
The controller 160 stores a table depicted in
The table is a table configured to indicate a relationship among the information indicating a color of foil, the manufacturer information indicating a manufacturer of the foil film F, and the target temperature. In a case where the manufacturer information is “Company A”, the controller 160 sets the target temperature to the standard temperature Tb (° C.). Here, since Company A does not manufacture the foil film F having dark colored foil or matte colored foil, the target temperatures for dark color and matte color are not set in the table.
In a case where the manufacturer information is “Company B” and the information indicating the color of the foil is gold or silver, the controller 160 sets the target temperature to “Tb+10 (° C.)”. In a case where the manufacturer information is “Company B” and the information indicating the color of the foil is dark, the controller 160 sets the target temperature to “Tb+10 (° C.)”. In a case where the manufacturer information is “Company B” and the information indicating the color of the foil is matte, the controller 160 sets the target temperature to “Tb+20 (° C.)”.
Note that, although not depicted in the drawing, the transferring part 50 includes a temperature sensor configured to detect the temperature of the heating roller 61. The controller 160 controls an electric current to be applied to at least one of the first heater 62 and the second heater 63 so that the temperature detected by the temperature sensor is the target temperature.
The controller 160 has a function of selecting at least one of the first heater 62 and the second heater 63, to perform the foil transfer, based on the information indicating the width and the position of the foil film F obtained from the memory 100. In this embodiment, the controller 160 applies an electric current to the first heater 62 and does not apply an electric current to the second heater 63 in a case where the information indicating the position of the foil film F and the information indicating the width of the foil film F obtained from the memory 100 is the “central position” and the “half width”. In a case where the information indicating the position of the foil film F obtained from the memory 100 is not the “central position” or the information indicating the width of the foil film F obtained from the memory 100 is not the “half width”, the controller 160 applies an electric current to both the first heater 62 and the second heater 63.
The controller 160 has a function of determining whether a remaining amount of the foil film F is in an empty state based on the usage history information obtained from the memory 100. The empty state is a state in which the remaining amount of the foil film F is a first predetermined amount or less. The controller 160 has a function of determining whether the remaining amount of the foil film F is in a near-empty state based on the usage history information obtained from the memory 100. The near-empty state is a state in which the remaining amount of the foil film F is a second predetermined amount, greater than the first predetermined amount, or less. In a case where the controller 160 determines that the remaining amount of the foil film F is in the near-empty state, the controller 160 reduces the conveying speed of the sheet S compared to a speed when the controller determines that the remaining amount of the foil film F is not in the near-empty state. Specifically, the controller 160 controls the conveying speed of the sheet S in the sheet conveying part 10 and the conveying speed of the sheet S and the foil film F in the transferring part 50 by controlling the rotation speed of the main motor M.
Next, the operation of the controller 160 will be described in detail.
In a case where the power of the foil transferring apparatus 1 is turned on, or in a case where the cover 22 is closed, the controller 160 executes the empty determining process in non-foil-transferring period depicted in
In the empty determining process in non-foil-transferring period, the controller 160 first determines whether a connection state between the memory 100 and the reader 150 is normal (S1). Here, the determining of whether the connection state between the memory 100 and the reader 150 is normal may be performed, for example, based on the voltage applied to the reader 150.
In a case where the controller 160 determines in the step S1 that the connection state is not normal (No), the controller 160 notifies an error indicating, for example, that the film cartridge FC is not attached to the housing body 21 (S2), and terminates the process. In a case where the controller 160 determines in the step S1 that the connection state is normal (Yes), the controller 160 obtains the usage history information from the memory 100 (S3).
After the step S3, the controller 160 determines whether the remaining amount of the foil film F is in the empty state, based on the usage history information (S4). In a case where the controller 160 determines in the step S4 that the remaining amount of the foil film F is in the empty state (Yes), the controller 160 notifies that the remaining amount of the foil film F is in the empty state (S5), and terminates the process.
In a case where the controller 160 determines in the step S4 that the remaining amount of the foil film F is not in the empty state (No), the controller 160 determines whether the remaining amount of the foil film F is in the near-empty state, based on the usage history information (S6). In a case where the controller determines in the step S6 that the remaining amount of the foil film F is in the near-empty state (Yes), the controller 160 notifies that the remaining amount of the foil film F is in the near-empty state (S7), and terminates the process. In a case where the controller 160 determines in the step S6 that the remaining amount of the foil film F is not in the near-empty state (No), the controller 160 terminates the process.
In a case where the controller 160 receives a foil transfer instruction for executing the foil transfer, the controller 160 executes the foil transfer process depicted in
After the step S21, the controller 160 determines whether the remaining amount of the foil film F is in the near-empty state, based on the usage history information (S22). In a case where the controller 160 determines in the step S22 that the remaining amount of the foil film F is in the near-empty sate (Yes), the controller 160 sets the conveying speed of the sheet S to a second speed, which is lower than a first speed used when the controller determines that the remaining amount of the foil film F is not in the near-empty state (S23).
After the step S23, the controller 160 sets the target temperature of the heating roller 61 based on the information indicating the color of the foil and the manufacturer information obtained from the memory 100 and the table in
In a case where the controller 160 determines in the step S25 that the width of the foil film F is the “half width” and the position of the foil film F is the “central position” (Yes), the controller 160 turns on only the first heater 62 (S26). In a case where the controller 160 determines in the step S25 that the width of the foil film F is not the “half width” or the position of the foil film F is not the “central position” (No), the controller 160 turns on both the first heater 62 and the second heater 63 (S27).
After the step S26 or the step S27, the controller 160 starts the foil transfer operation (S28). Specifically, in the step S28, the controller 160 starts conveying of the sheet S by driving the main motor M in a case where the temperature of the heating roller 61 reaches a temperature close to the target temperature. Then, at the timing when the sheet S reaches the transferring part 50, the controller 160 press the heating roller 61 against the pressure roller 51 and rotate the heating roller 61 and the pressure roller 51 so as to convey the sheet S and foil film F by the nip part of the transferring part 50 and transfer the foil onto the sheet S.
After the step S28, the controller 160 calculates a length of the foil film F having been used for one sheet S (S29). Note that, in the following description, the length of the foil film F having been used is also referred to as a “used length”. In addition to the method described above, the used length of the foil film F can also be calculated based on, for example, the peripheral length and the number of rotations of the pressure roller 51 in a time period in which the heating roller 61 is pressed against the pressure roller 51.
After the step S29, the controller 160 calculates a total used length by adding the used length of the foil film F calculated in the step S29 to the usage history information, and determines whether the remaining amount of the foil film F is in the empty state based on the total used length (S30). Note that, in a case where the controller 160 performs the foil transfer on the second or subsequent sheets S, the controller 160 calculates the total used length in the step S30 by adding the used length of the foil film F calculated in the step S29 to the previously calculated total used length.
In a case where the controller 160 determines in the step S30 that the remaining amount of the foil film F is not in the empty state (No), the controller 160 determines whether the foil transfer to the sheet(s) S as much as the number specified by the foil transfer instruction has been completed (S31). In a case where the controller 160 determines in the step S31 that the foil transfer has not been completed (No), the controller 160 returns to the process of the step S28 to start the foil transfer to the next sheet S.
In a case where the controller 160 determines that the foil transfer has been completed in the step S31 (Yes), the controller 160 terminates the foil transfer operation (S33). Specifically, in the step S33, the controller 160 stops the main motor M and turns off both the first heater 62 and the second heater 63.
In a case where the controller 160 determines in the step S30 that the remaining amount of the foil film F is in the empty state (Yes), the controller 160 notifies that the remaining amount of the foil film F is in the empty state (S32), and terminates the foil transfer operation (S33). After the step S33, the controller 160 writes the total used length into the memory 100 (S34), and terminates the process.
Next, specific examples of the operation of the controller 160 will be described.
In the foil transfer process, in a case where the information indicating the color of the foil and the manufacturer information obtained by the controller 160 from the memory 100 is “gold” and “Company A”, respectively, the controller 160 sets the target temperature of the heating roller 61 to Tb (° C.) and executes the foil transfer. In the foil transfer process, in a case where the information indicating the color of the foil and the manufacturer information obtained by the controller 160 from the memory 100 is “gold” and “Company B”, respectively, the controller 160 sets the target temperature of the heating roller 61 to Tb+10 (° C.) and executes the foil transfer. Therefore, the controller 160 can execute the optimal foil transfer according to the material of the foil film F manufactured by each manufacturer.
In the foil transfer process, in a case where the information indicating the color of the foil and the manufacturer information obtained by the controller 160 from the memory 100 is “matte color” and “Company B”, respectively, the controller 160 sets the target temperature of the heating roller 61 to Tb+20 (C) and executes the foil transfer. Therefore, the controller 160 can execute the optimal foil transfer according to the difference in the color of the foil.
In a case where the controller 160 executes the foil transfer process in a state that the second film cartridge FC2 depicted in
According to the above, the present embodiment achieves the following effects.
The controller 160 changes the amount of heat to be given to a unit area of the foil film F from the heating roller 61 based on the information indicating the type of the foil film F obtained from the memory 100. Therefore, the controller 160 can perform the foil transfer appropriately, by using the information in the memory 100 of the film cartridge FC.
The controller 160 sets the target temperature suitable for each color of the foil. Therefore, the controller 160 can perform the foil transfer appropriately.
Even if a material of the foil film F varies manufacturer by manufacturer, the controller 160 sets the target temperature suitable for each manufacturer. Therefore, the controller 160 can perform the foil transfer appropriately.
In a case where the remaining amount of the foil film F is in the near-empty state, the controller 160 reduces the conveying speed of the sheet S. Therefore, even if the foil film F breaks and separates from the supplying reel 31 in a case of empty, occurrence of catching of the broken end of the foil film F into the transferring part 50 can be reduced.
The controller 160 performs selection regarding the first heater 62 and the second heaters 63 based on the information indicating the width and the position of the foil film F stored in the memory 100. Therefore, the cost can be reduced compared to a configuration, for example, including sensor(s) configured to detect the width and the position of the foil film F.
